The Irwin Drill Bit Set offers 29 pieces ranging from size 1/16 inch to 1/2 inch. Made from cobalt, these metal drill bits have been created with heavy-duty materials for ultimate strength and durability. You can use these drill bits to drill through tough metal. In fact, you can even use them to drill through hardened steel.
Another nice feature of these drill bits is the design. They have been specifically designed with a 135-degree split point tip, so a drill bit “walking” across the surface is a thing of the past.
This 29-piece drill bit kit is presented in a metal index case, which gives you easy access when you need to access the pieces quickly. The case also features an outer rubber molding, which prevents damage if you drop the kit.
